JOHN M. AXTMANN, OF NEW YORK, N. Y.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 223,305, dated January6, 1880.

Application filed October 30, 1879.

invented a new and Improved Transom-Lifter,

of which the following is a specification.

The object of my invention is to provide a new and improved attachmentfor transoms, by means of which they can be conveniently opened and heldin the desired position.

The invention consists in a curved lever pivoted to a bracket secured tothe door'frame,

and having one end pivoted to a pitman-rodprovided with a handle orknob, and the other end provided with a stud which passes into a slot inan angle-plate securely attached to the hinged or pivoted transom.

In the accompanying drawings,iFigure 1 is a front elevation of a transomprovided with my improved opening device. Fig. 2 is a side elevation ofan open transom provided with my improved opening device. Fig. 3 is aside elevation of the same, showing the transom closed.

Similar letters of reference indicate corresponding parts.

A bracket, A, is securely fastened to the frame B of a transom, O, andhas a curved or forked lever, D, pivoted to it by means of a screw, 61.The upper end of the lever D terminates in the two arms E and E to oneof which the curved pitman-rod F, flattened at its lower end andprovided with a knob, G, is pivoted by the screw f. The flat part of therod F is provided with one or more perforations, H H, through which apin, I, fastened to the door or window frame J, can pass, and thus holdthe rod in any desired position. The perforations H have an elongationwhich is narrower than the perforation itself, and as the pin I isprovided with a head the rod cannot be unhooked by shaking or pushing,and can never be loosened by the wind or storm. The pin I and aguide-staple, K, are fastened to a plate, L, which is secured to thedoor-frame J.

The other end of the lever D is provided with a laterally-projectingstud, M, which passes into the slot N (which may be straight or curved)of an angle-piece, O, firmly attached to the transom G. I

The angle-piece O is provided with a slot, N, in the side fastened tothe transom, so that it can be used at either side of the transom.

The transom may be hinged at the top or bottom, or may be pivotedcentrally.

The operation is as followsrThe transom being closed, as is shown inFig. 3, to open it the rod F is drawn in the direction of the arrow a.This will cause the arm E of the lever D to move in the direction of thearrow 1) and the stud M to movein the direction of the arrow 0. The studM glides in the slot N and opens the transom G in the direction of thearrow 0. As soon' as the transom is in the desired position the rod F isheld by passin g the corresponding aperture H over the pin I, as isshown in Figs. 1 and 2.

By reversing the above movements the transom is closed.

In case it is desired to attach the apparatus to the other side of thesame surface of the transom, the angle-piece O is attached to the otherside, so that the flange with the slot N lies against the frame and theslot N is presented to the stud M. The lever D is pivoted on theopposite side of the bracket A, and the rod F is pivoted to the arm Ethe bracket A and plate L having been attached to the door or windowposton the corresponding side. The operation will be as described above.

If the transom is PiXObGd centrally or hinged below, the position of theangle-piece 0 must be higher or lower on the transom.

I am aware that transom-lifters provided with a slotted plate haveheretofore been used; but this I do not claim, broadly; but,

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. The combination, with the transom U, of the slottedangle-plate O, the lever D, the stud M, the bracket A, and the rod F,substantially as herein shown and described, and for the purpose setforth.

2. In a transom-lifter, the anglepiece 0,

side of the transom substantially as herein shown and described, wherebythe transom 10 can be operated from either side with the same J. M.AX'IMANN.
